Made from 100% recycled material, these tiles are ideal for early numeracy skills. Children can easily connect the tiles together and take them apart again. The tiles are colour coded to show even numbers in blue, odd numbers in yellow, and operations in red. Each set contains 52 number tiles with numbers on one side and a subitising pattern on the reverse side apart from zero, 22 single sided operation tiles (plus, minus, equals, greater than and less than), and 24 double sided A5 workcards. The 24 workcards are colour coded across 3 levels: numbers up to 10, numbers up to 20, and addition and subtraction questions to 20. Ideal for several children to use at the same time. Each tile measures 6cm and is extremely hard wearing. Age: 2+.
